Top Alternatives to Askar SQA70 for Astrophotography Enthusiasts
If you’re exploring refractor telescopes for astrophotography, the Askar SQA70 often comes up as a compelling option due to its optical design and feature set. However, depending on your budget, experience level, portability needs, or specific imaging goals, it may not be the ideal fit. This guide helps you understand when the Askar SQA70 fits best and walks you through practical alternatives tailored to varied astrophotography scenarios. Whether you prioritize price, portability, or optical performance, you will find insights to choose the refractor that truly suits your needs.
Why Buyers Consider the Askar SQA70
The Askar SQA70 appeals primarily to intermediate and advanced astrophotographers seeking a compact refractor optimized for deep sky imaging. Its quintuplet optical design delivers a flat, coma-free field that ensures sharp stars from edge to edge, an essential feature for those using full-frame or APS-C cameras. This optical precision supports capturing detailed wide-field views of nebulae, galaxies, and star clusters with minimal aberrations.
Beyond optics, the Askar SQA70 integrates features that enhance astrophotography workflows. It includes a built-in dew shield to reduce moisture buildup during long sessions, a high-quality dual-speed focuser for precise adjustments, and compatibility with electronic automatic focusers (EAF), filter wheels, and off-axis guiders (OAG). These accessories are critical for serious imagers who require reliable focus control and guiding precision.
Portability is another draw. Weighing less and measuring smaller than many equivalent refractors, the Askar SQA70 is designed for field use without the bulk associated with larger telescopes. Its 70 mm aperture and 336 mm focal length balance light gathering and a moderately wide field of view, suitable for a broad range of deep sky targets.
When the Askar SQA70 Is the Wrong Fit
Despite its strengths, the Askar SQA70 is not for everyone. Beginners or those on a strict budget may find its price point (~$319) and additional accessory requirements (field flatteners, reducers, compatible mounts) beyond their comfort zone. Its advanced features and optical design require some familiarity with astrophotography gear to fully leverage, which can present a steeper learning curve.
Additionally, although portable relative to some refractors, it is heavier and bulkier than ultra-compact models. Buyers prioritizing travel-friendly setups or those with smaller capacity mounts should consider lighter alternatives to avoid overloading equipment or complicating transport. The Askar SQA70’s mounting needs also exclude very small or lightweight mounts, narrowing its compatibility window.
Finally, users focused on planetary or lunar imaging might find the 70 mm aperture and 336 mm focal length less optimal compared to scopes with longer focal lengths or larger apertures tailored for high magnification and resolution on bright objects.
Better Alternatives for Different Astrophotography Scenarios
1. Budget-Conscious Beginners and Backyard Astrophotography
For those starting out or working within a tighter budget, the Sky-Watcher 72ED, Astro-Tech AT-60 ED, and William Optics Zenithstar offer compelling value. These refractors provide good optical quality with simpler mechanics, making setup and use more approachable for novices. They are also significantly less expensive than the Askar SQA70, easing entry into astrophotography without large initial investments.
- Sky-Watcher 72ED: Offers good optics at an accessible price. It’s lightweight and suitable for users upgrading from basic scopes. While it requires additional field flatteners for optimal full-frame imaging, it balances quality and affordability well.
- Astro-Tech AT-60 ED: Known for solid mechanical construction and portability. Its doublet design means color correction is not as advanced, but it’s well suited for budget setups and lightweight mounts.
- William Optics Zenithstar: Affordable and user-friendly with decent optics for entry-level astrophotography. Aperture is smaller, which limits light gathering but enhances portability.
These options are ideal if you want easy setup, portability, and respectable image quality without the complexity or cost of advanced flat-field quintuplet designs.
2. Intermediate Astrophotographers Seeking Balanced Performance and Price
Buyers with some experience who want to improve imaging quality but remain price-conscious often consider the Sky-Watcher Evostar 72ED. This refractor delivers better optics than entry-level options and is more affordable than the Askar SQA70. Its optical design is suitable for deep sky imaging but generally requires additional flatteners or reducers for full-frame cameras.
The Evostar 72ED is lighter, making it easier to handle and compatible with a wider range of mounts. This makes it a practical choice for backyard astrophotographers who want to step up their imaging without investing in the more complex and heavier quintuplet systems.
3. Advanced Astrophotographers Prioritizing Optical Excellence and Portability
For users focused on image quality and portability, the ZWO FF65 APO and Askar 71F Flat-Field present strong alternatives. Both are high-quality refractors offering flat-field optics and excellent color correction. The ZWO FF65 APO is noted for slightly tighter star images and superior color correction compared to the Askar SQA70, making it attractive for those emphasizing optical purity.
The Askar 71F Flat-Field, while similar in optical design, is favored by some for its balance of flat-field correction and moderate price. However, it is heavier and less portable than the SQA70, which might affect mount compatibility and transport convenience.
These models suit astrophotographers who have experience managing more complex setups and want to maximize image quality with relatively portable equipment, accepting the higher price and accessory needs.
Best Choice by Buyer Type
Beginners and Budget Buyers
If you are new to astrophotography or have a limited budget, prioritize ease of use and affordability:
- Sky-Watcher 72ED or William Optics Zenithstar for a balance of optical quality and price.
- Astro-Tech AT-60 ED if portability and mechanical robustness are top priorities.
These options require fewer accessories and are easier to handle with lightweight mounts, ideal for backyard imaging and initial learning phases.
Intermediate Users Seeking Value and Versatility
Astrophotographers with some experience wanting to improve image quality without a large price jump should consider the Sky-Watcher Evostar 72ED. It offers better optics and compatibility with a wider range of mounts while maintaining affordability. This refractor is well suited for deep sky imaging enthusiasts upgrading from beginner gear.
Advanced Users Focused on Optical Performance and Portability
For those who prioritize the highest optical quality and portability within the refractor class, the ZWO FF65 APO and Askar 71F Flat-Field are strong alternatives. Choose the ZWO FF65 APO if superior color correction and star sharpness are your main criteria. Opt for the Askar 71F if you want a flat-field design with a slightly more accessible price, but be aware of its weight and mount requirements.
If you find the Askar SQA70 appealing but want a more compact or lightweight option with similar optical strengths, these models merit consideration.
Final Recommendation
The Askar SQA70 stands out as a versatile, high-quality quintuplet refractor tailored for intermediate to advanced astrophotographers who seek flat-field, coma-free wide-field imaging with full-frame cameras. Its features like a built-in dew shield, electronic focuser compatibility, and sturdy mechanical design support demanding imaging setups. However, its price and weight make it less suitable for beginners, budget-conscious buyers, or those needing ultra-portable travel scopes.
For beginners or those prioritizing value and simplicity, budget-friendly refractors such as the Sky-Watcher 72ED, Astro-Tech AT-60 ED, or William Optics Zenithstar offer accessible entry points with decent optics and manageable setups. Intermediate users ready to enhance image quality without significantly increasing cost will find the Sky-Watcher Evostar 72ED a practical step up.
Advanced astrophotographers seeking top-tier optical performance and portability should consider the ZWO FF65 APO or Askar 71F Flat-Field as alternatives with subtle tradeoffs in price, weight, and mount compatibility.
Ultimately, your choice should align with your astrophotography goals, budget, mount capacity, and willingness to manage accessory complexity. The Askar SQA70 is a balanced option for serious imagers who can accommodate its demands, while the alternatives provide tailored solutions for a range of budgets and experience levels.
